With no competition likely as a result, this should be a nice little earner for AW/WHL.
Remember the Prime Contractor for the Merlin Mk1 was and may still be Lockheed Martin not AW, so not sure their would be much money or work in it for AW/WHL.
More likely to be more money/work for Thales or whoever get to develop a radar to fit into the Merlin.
